dev-cpp-users Mailing List for Dev-C++ (Page 732)

        I have a program that can run either in user entry mode (prompts
user) or in automatic mode ( no user entries --- I just schedule it with
Windows Task Scheduler).  It runs in automatic mode when given a command
line parameter of "auto."

        Question:  Is there some simple way to have it use the console in
user entry mode but have it not use the console (run in background) when it
is running in automatic mode?

Thanks, Alan

I was referred to use this instead of if / else statements I’m trying to
understand how to use it I have read the article on MSDN I ask can someone
write a small program that will get the variable from the keyboard and a
small action for instance if you enter 1 it says the number 1 detected or Z
would say the letter z detected as when I see this in use I can fully
understand how to use it thanks :O)

In many cases you would like to use "normal" variables like:

Example:
int x;

However, in practice it is often difficult to predict the number of
variables you will have to proces. How many lines will there be in a
book that you scan? How many record are there in an email addreslist?
In such cases you may want to work with "dynamic" memory. Then you need
those pointers to be able to find and retreive the data in/from the
computers memory.

Another advantage of pointers:
In stead of moving huge amounts of data in function calls it is often
faster to use a pointer to the data.

Example:
int x[100000];
int main() { my_function(x); } // Huge memory and time needed.
int main() { my_function(&x); } // Very fast and efficient

Hope this helps

I want to create a 3D modeller in C++ and I am looking for existing material to
setup 3D classes (objects like spheres, planes, torusses, etc.) and 3D scenes
(with camera's, lights, etc).

Any "links" available?

can any one help me i'm just starting learing about c/c++ en use the compiler 
dev c++
and I'm getting error stdprn undeclared!!!!!!!!

  Please can some one help me: Who knows an excellent
text book  for  Data structures via C++, or a good web
 site that i can use to learn data structures  via
C++.
Thanks.

Hi Devik,
I copied and pasted your code below and compiled it using Dev-C++ and =
there were no errors found.  It compiled fine but I could not run it =
successfully (which must be a problem with my compiler - as all my =
programs have compiled fine but refuse to run).  Best of luck!=20

  Hi
  I am a student learning c++ and have written a program to displace =
fibonacci numbers till the value entered by the user. This program =
doesnt compile in DevC++ showing some linker errors however it does =
compile in Visual c++. Any Ideas on whats wrong ?
  Thanks
  Devik

  Here's the code

  /* This Program Displays N Fibonacci Numbers */
  #include<iostream.h>


  void main()
  {
  int c,a=3D1,b=3D1,newno,n;
  cout<<"Enter the value of n ";
  cin>>n;
  cout<<"\nThe N Fibonacci Numbers are \n";
  cout<<a<<" "<<b<<" ";
  for(c=3D2;c<=3Dn;c++)
  {
  newno=3Da+b;
  a=3Db;
  b=3Dnewno;
  cout<<newno<<" ";   }

  }

hi there, i've got two questions if someone could answer them for me.

does anyone know:
1) how to do a function that only gives a limited time for you to      
answer a question?

2) how to produce a tone through the pc's internal speaker?

it would be much appreciated if anyone could shed some light on this.

I have been trying to use a dll (QCard32.DLL) to create a simple card
program with Dev-C++ 4.1.  I have added the qcard32.lib file to the Project
Options -- and included the qcard32.h header file in the main.cpp file.  I
have added a menu item to try and show one card -- including two function
calls:  one to initialize the deck and the other to deal one card.
Everything compiles and links just fine -- the dll is located with the
executable and in the //windows/system directory.  But when I try to execute
the program, I get the following dialog box messages:

"The cardtest.exe file is linked to missing export QCARD32.DLL:."

and

"cardtest.exe     A device attached to the system is not functioning."

I know that the DLL and LIB files are okay.  I have used them in a VB5
application and with XBasic.  Does anyone have any suggestions or advice on
what I am doing wrong?  You help is appreciated.

I have recently purchased a c++ book...and it asked to do the following 
program:
A perfect number is a positive integer such that the sum of the proper 
divisors equals to the number. Thus, 28=1+2+4+7+14 is a perfect number. If 
the sum of the divisors is less than the number, it is deficient. If the sum 
exceeds the number, it's abundant.
a) Write an interactive program that allows the user to enter a positive 
integer and then displays the result, indicating whether the number entered 
is perfect, deficient, or abundant.
b) Wrtie another interactive program that allows the user to enter a 
positive integer N and then displays all perfect numbers less than or equal 
to N.
*Program should allows the user the option of continuing or quitting*

Any help would be appreciated...thanks!

I beg your pardon! "this n with a ~ above it" is the 25th letter of the Spanish alphabet, and means to me exactly the same as any other letter of the alphabet could.

Has the code any relation with Spanish? I mean, is there a list of names or something like that? If not may be they used it for other purposes.

Just type ALT+164 and you'll get the character

Garland,
                Did you get this code off this list or off some other email?
Could it be that the extra junk is really a result of somebody sending you
an email in HTML format?  I`ve seen that in some emails on this list, esp.
with the "3D."

Subject: [Dev-C++] C++

I came across a piece of code that looks funny, it has a n with ~ above =
it. Ex. c =3D (anc) with ~ above the n. What does it mean, and how do =
you put the ~ above the n.=20

Does anyone else ever get an error message "Access violation at address
004E52EA in module 'DEVCPP.EXE.'   Read of address 012DC063." when
compiling?  When I get this error, sometimes I have to exit Dev-C++ and then
start it up again.  I am using version 4.01.


Thanks, Alan

Jag,
        I think you need "()" when you call your function, even if the
parameter is a void.  Better yet, why don`t you pass your variables to your
functions?  It is best to avoid global variables whenever possible.

        Better naming of things (functions, variables, etc.) would make your
program more readable.  There are also better styles for checking the
validity of input.  For example, how about the following rewrite of your
program....

#include <stdio.h>
#include <iostream.h>
#include <stdlib.h>

void function_1 (int int_in);
void function_2 (int int_in);

int main(int argc, char *argv[])

{
int input;

  int Validated_Input = false;

  while (!(Validated_Input))
        {
         cout <<"monkey type (1) for function 1 or (2) for function 2: ";
         cin >> input;
         if ((input == 1) || (input == 2))
            Validated_Input = true;
         else
              {
               Validated_Input = false;
               cout << endl << " Invalid entry. Try again." << endl;
              }
         }

  if (input == 1)
     function_1(input);
  else if (input == 2)
          function_2(input);

  system("PAUSE");

  return 0;
}


void function_1 (int int_in)
{

cout <<"calling function "<<int_in << endl;

}
void function_2 (int int_in)
{


cout <<"calling function "<<int_in << endl;

}

    You probably added at literally at the end.  Add it just before the
closing bracket (}).

Also adding the return 0; gave me another error parse error before return

I have the book, this n with a ~ above it is a typo, it doesn't mean
anything (in the context of the exercise).

 site that i can use to learn data structures  via
C++.
Thanks.
